"Operation Dynamo" was the code name for the evacuation of British and Allied troops from the beaches of Dunkirk, France, during World War II. This operation took place from May 26 to June 4, 1940, as German forces advanced rapidly through France, trapping the Allied soldiers. The goal was to rescue as many troops as possible and bring them back to Britain. The evacuation involved a large-scale effort, utilizing military ships and civilian vessels, including fishing boats and pleasure crafts. Approximately 338,000 soldiers were successfully evacuated, which became a significant morale boost for the Allies in the early stages of the war.
